Hi,

Interesting article! Have you read the article yet, as I make reference to specific pages and tables in the article? One approach to helping you with an assignment like this one is to address each question and also provide the page number of the information for more detail. This is the approach this response takes, which is in keeping the BrainMass policy which states that OTAs are NOT to complete assignments or part of assignments for students. However, I provide enough information for each question that it should be fairly easy to take it to the next step of writing your final copy.

Let's take a closer look.

RESPONSE:

1. What is the purpose of the study?

The purpose of study 1 is to examine the probabilities assigned by delusional persons to delusional beliefs to test the Bayesian model. The purpose of study 2 is to examine the role played by familiarity with the context of the delusional narratives in the participants of their probabilities (see p. 4).

2. What is the problem, theory, and/or research context that gave rise to the study.

A fundamental tenet of the Bayesian model is the reasoning bias in that persons who are delusional during hypothesis evaluation seems to be the bias in data-gathering rather than a deficit in probability reasoning as suggested by past research. In other words, the authors recognize the importance of past research, which suggests that that delusional persons formulate probability estimates faster than nondelusional persons after gathering less information. Even though the authors recognize this past research contributions, they believe that a more valid and naturalist test of the Bayesian model would be to examine the probabilities assigned by delusional persons to delusional beliefs (p. 2). This gave rise to this study.

3. What is the research question(s) and major hypotheses.

Interesting, and indeed a weakness of the study is that neither the research question nor the major hypotheses are clearly stated. However, one can go to the introduction and the results section and infer the research question and the hypotheses, respectively.

What are the probabilities assigned by delusional persons to delusional beliefs, and do they differ from nondelusional persons? Do delusional persons overestimate (e.g., reasoning bias) the probability of delusional beliefs?
Was the reasoning bias found in Study 1 specific to delusional content or general to other types of content?

· Nondelusional people will estimate will estimate different probabilities for delusional narratives than delusional persons.
· Experimental groups will estimate different probabilities for delusional narratives than racial groups.
· The probabilities assigned by delusional people are ...
